What do you think of Interactive EBook?

Hi,

  I have an idea of interactive ebook which allows you to interact with the book you are reading with following features - 

1. Make notes on ebook page and see other user's notes. 2. Mark/highlight parts of ebook content. 3. Both highlighted content and notes are searchable. 4. Add dynamic behaviour to pages. For ex., if the book is about Java, allow snippets of code to be executed from the book itself. Also you can edit the code and execute the changed code and see the output.

  Is anybody interested reading such an ebook?

Thanks -- pkc
